[PATCH openEuler-1.0-LTS] usb: gadget: f_fs: Prevent race during ffs_ep0_queue_wait
by Guo Mengqi 25 Apr '25

25 Apr '25

From: Udipto Goswami <quic_ugoswami(a)quicinc.com> stable inclusion from stable-v4.19.272 commit e9036e951f93fb8d7b5e9d6e2c7f94a4da312ae4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBWVWG CVE: CVE-2022-49755 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 6a19da111057f69214b97c62fb0ac59023970850 ] While performing fast composition switch, there is a possibility that the process of ffs_ep0_write/ffs_ep0_read get into a race condition due to ep0req being freed up from functionfs_unbind. Consider the scenario that the ffs_ep0_write calls the ffs_ep0_queue_wait by taking a lock &ffs->ev.waitq.lock. However, the functionfs_unbind isn't bounded so it can go ahead and mark the ep0req to NULL, and since there is no NULL check in ffs_ep0_queue_wait we will end up in use-after-free. Fix this by making a serialized execution between the two functions using a mutex_lock(ffs->mutex).

From: Miaoqian Lin <linmq006(a)gmail.com> mainline inclusion from mainline-v6.15-rc1 commit 6171063e9d046ffa46f51579b2ca4a43caef581a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC2CBV CVE: CVE-2025-38575 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Use aead_request_free() instead of kfree() to properly free memory allocated by aead_request_alloc().

[PATCH OLK-5.10 1/2] sched/dynamic_affinity: fix preffered_cpu offline problem

23 Apr '25

From: He Yujie <coka.heyujie(a)huawei.com> Offering: HULK hulk inclusion category: bugfix bugzilla: 190373 -------------------------------- After the preferred_cpu goes offline, the core selection of dynamic affinity does not check whether the preferred_cpu is valid.

[PATCH openEuler-1.0-LTS] vlan: enforce underlying device type
by Wang Liang 23 Apr '25

23 Apr '25

From: Oscar Maes <oscmaes92(a)gmail.com> mainline inclusion from mainline-v6.14-rc6 commit b33a534610067ade2bdaf2052900aaad99701353 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBVPBN Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Currently, VLAN devices can be created on top of non-ethernet devices. Besides the fact that it doesn't make much sense, this also causes a bug which leaks the address of a kernel function to usermode. When creating a VLAN device, we initialize GARP (garp_init_applicant) and MRP (mrp_init_applicant) for the underlying device. As part of the initialization process, we add the multicast address of each applicant to the underlying device, by calling dev_mc_add. __dev_mc_add uses dev->addr_len to determine the length of the new multicast address. This causes an out-of-bounds read if dev->addr_len is greater than 6, since the multicast addresses provided by GARP and MRP are only 6 bytes long. This behaviour can be reproduced using the following commands: ip tunnel add gretest mode ip6gre local ::1 remote ::2 dev lo ip l set up dev gretest ip link add link gretest name vlantest type vlan id 100 Then, the following command will display the address of garp_pdu_rcv: ip maddr show | grep 01:80:c2:00:00:21 Fix the bug by enforcing the type of the underlying device during VLAN device initialization.

[PATCH openEuler-1.0-LTS] tracing: Fix use-after-free in print_graph_function_flags during tracer switching
by Tengda Wu 23 Apr '25

23 Apr '25

From: Tengda Wu <wutengda(a)huaweicloud.com> mainline inclusion from mainline-v6.15 commit 7f81f27b1093e4895e87b74143c59c055c3b1906 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC1QR9 CVE: CVE-2025-22035 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Kairui reported a UAF issue in print_graph_function_flags() during ftrace stress testing [1]. This issue can be reproduced if puting a 'mdelay(10)' after 'mutex_unlock(&trace_types_lock)' in s_start(), and executing the following script: $ echo function_graph > current_tracer $ cat trace > /dev/null & $ sleep 5 # Ensure the 'cat' reaches the 'mdelay(10)' point $ echo timerlat > current_tracer The root cause lies in the two calls to print_graph_function_flags within print_trace_line during each s_show(): * One through 'iter->trace->print_line()'; * Another through 'event->funcs->trace()', which is hidden in print_trace_fmt() before print_trace_line returns. Tracer switching only updates the former, while the latter continues to use the print_line function of the old tracer, which in the script above is print_graph_function_flags. Moreover, when switching from the 'function_graph' tracer to the 'timerlat' tracer, s_start only calls graph_trace_close of the 'function_graph' tracer to free 'iter->private', but does not set it to NULL. This provides an opportunity for 'event->funcs->trace()' to use an invalid 'iter->private'. To fix this issue, set 'iter->private' to NULL immediately after freeing it in graph_trace_close(), ensuring that an invalid pointer is not passed to other tracers. Additionally, clean up the unnecessary 'iter->private = NULL' during each 'cat trace' when using wakeup and irqsoff tracers.

With BPF progs mixing bpf2bpf and tailcalls, build_prologue() generates N insns in the first pass and then generates N+1 insns in the second pass. This makes epilogue_offset off by one and we will jump to some unexpected insn and cause lockup. Fix this by inserting a nop insn.
